To all whom 2'25 may concern:

Be it known that I, EUGENE BROUQUIERE,

a citizen of the French Republic, residing:

at Salchan, Hautes-Pyrnes, France, have invented certain new and useful Improvements in Steam Supply Valves with Pendu-. him-Governors for Ships Engines, of which.

the following is a specification.

Upon the steam pipes which engines there exists near the slide valve of the engines a steam parallel slide stop valve or gate valve or regulating flap valve which When the: sea is rough, it frequently happens that the propellers get out of the water and turn in the air where they find scarcely any res1stance. The speed of the engines consequently considerably increases so that it becomes dangerous for the moving parts of the en-. gines. Generally, this inconvenience is overcome by operating the regulating flap valve; by hand so as to reduce the steam supply;

regulates the steam admission.

or even to shut the steam off. This opera-.

tion is, however, very delicate and difficult.

It therefore has been proposed to use mechanical means for automatically producing the desired effect. None of the devices of known construction gives, however, com-; plete satisfaction.

This invention relates to a slide valve combined with a pendulum governor. The pendulum is arranged so that it swings in. the longitudinal axis of the ship. It drives the slide valve through the intermediary of an equilibrated beam. The principal condition to be fulfilled if this apparatus has to work properly is the reduction of friction and the good equilibration of the beam so that all the energy of the pendulum is rapidly transmitted to the slide valve or to the flap valve. The connection between the pendulum and the slide valve is adjustable so that the normal position of the pendulum corresponds with an initial position of the slide valve which can be modified according to the draft of the ship and to the amplitude of the oscillations resulting from the pitching. The pendulum can further be separated from the slide valve which thus can be directly driven by a hand-wheel as is ordinarily the case.

In the drawings the improved apparatus is shown by way of example.

Figure 1 is an elevation of the improvedsteam supply valve with pendulum regulators. Fig. 2 is a vertical section through I Fig. 1. Fig. 3 is a vertical section taken at right angles to the section shown in Fig. 2.

The casing 1 (Fig. 1) has a feed nozzle 2 which communicates, by means of ports 3, with an annular space 4 which is connected with a pipe 5 fixed upon the slide valve box of the engines. The ports 3 can be covered,

more'or less, by a slide valve 6 which is feed a ships.

rigidly connected with a piston 7. This piston is connected by a connecting rod 8 with the end 9 of a beam 10, the other end 11 of this beambeing connected by means of a connecting rod 12 with a second piston 13 of the same diameter as the first piston, but of a weight which is equal to that of the piston 7, plus the weight of the slide valve 6. A passage 14 serves for connecting the space above the piston 13 with the steam nozzle 2. In the top part of the slide valve 6, perforations are provided through which the steam can get at the piston 7. The beam carries a pinion 15 which meshes with a toothed segment 16 keyed upon a shaft 17 which further carries a hand-wheel 18. In front of this hand-Wheel 18 the rod 20 of the pendulum 21 is loosely mounted upon said shaft 17. The rod 20 has a lateral arm 22 which is slotted and serves as guide for a threaded connecting rod which is fixed with the other end to the pin 24. of the handwheel, and which is secured in its position by two regulating nuts 25 and 26.

The lower part of the casing 1 forms an oil reservoir 27 adapted to be filled by a lateral channel 28. An air hole 29 serves for the escape of the air from said oil reservoir. At the bottom of the oil reservoir 27 a valve controlled blowoff port 30 is arranged which also serves for blowing off the water from condensation.

This apparatus operates as follows :The plane of oscillation of the pendulum coincides with the longitudinal plane of the ship. The apparatus is arranged in such a manner that when the stern of the ship gets out of the water, the corresponding movement of the pendulum makes the slide valve 6 move upward and throttle the steam ports. In Figs. 1 and 2 of the drawings the bow of the ship is supposed to be at the right hand side of the figureand the stern at the left hand side of the same.

The slide valve 6 is not in contact with the wall of the cylindrical boring in which it moves so that even if the steam ports 3 were completely closed, there will always flow a sufficient amount of steam which, together with the action of the vacuum condenser, prevent the stopping of the engines.

The diameter of the pistons 7 and 13 is slightly shorter than the inner diameter of the cylindrical boring in which they are locatedf Said pistons are made tight by means of circular grooves arranged the one above the other and forming corresponding chamhers for the steam.

The lower part 27 of the casing 1 is completely filled with oil so that the pistons and all the gearing are completely immersed in the oil. The journal of the shaft 17 is very long and it also has circular grooves whereby the escape of oil is prevented.

The initial position of the slide valve 6 corresponding to the vertical position of the pendulum 21 can be regulated by means of the nuts 25 and 26 and of the hand 31. 711cm the position of the slide valve is'regulated the actual draft of the ship has to be taken into account which, of course, varies according to the load of the ship. \Vhen the sea is calm the connecting rod 23 can be disconnected from the pendulum 21 when the hand wheel 18 alone serves for the operation of the slide valve as with an ordinary steam admission. The rolling of the ship has no influence upon this apparatus owing to the arrangement according to which, the plane of oscillation of the pendulum coincides with the longitudinal plane of the ship.
